Dust Masks x 10

These dust masks are used when mixing the absorbent powders in type HK mercury spillage kits. They provide protection against inhalation of calcium hydroxide and sulphur dust during mixing and use, but do not provide protection against mercury vapour, for which the mercury vapour mask is available on this site. The pack is for replensihment or replacement of masks in multiple standard type HK kits such as in the hospital or industrial setting.
